Recoloring seats?

[WinDancer]

I have a set of good cloth seats for the truck. They are the wrong color [aren't they always?].

What are you guys using to make them a different color?

Seems like there are many, many brands out there... your favorite?

I want to do them two-toned Black and Blue using masking tape to separate the colors... am I asking for trouble or would I be better off with a single color?

Thanks!
